  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Advice needed: 2010 TE 250 xlite Camshaft disaster

Hi all,
I'm a husky owner from Sweden, in need of some advice from the experts in this forum. I tore down the top end to do a simple piston change, and found a broken cam shaft in there. The cams are absolutely fine otherwise, no engine noise, no excessive wear on the top end, but a piece was loose from the (dont know the term) ring which fixates the cam in axial direction. See pictures. The piece has not come loose during my disassembly, I can tell because the fracture does not look fresh and the aluminium in the top end has small scratch marks from running in this condition. Since this part of the cam is fully enclosed, the piece had nowhere to go but remained fixed.

I suppose I should get a new cam shaft, but they are quite pricey. In your opinion, do I have any options? Welding seems extremely hard? Removing the piece and rounding of the corners has struck me as a way forward. It's not like there is a lot of pressure on this piece. Could that cause any unhealthy unbalance? Any advice or comment welcome.

Kind regards,
Peter

A new cam is not going to be cheap but wouldn't like to use that cam in that condition, even though it may run ok at first it would always be in the back of my mind and it would do serious damage if it failed at 13000rpm and probably write the entire top end off. It could be welded and then machined back into spec on a lathe by any decent engineer.
 
Unfortunately the answer is no you have no choice. If you want the bike to run properly you'll need to replace it. If you don't you will eventually drive shavings into the rest of the motor because unless your going to Percision grind and somehow balance the cam it will vibrate and create shaving that will end up in the bearings and blow the motor.

I had a DRZ blow up when the exhaust cam seized to the head because it had lost oil and coolant. It was junk in the end there wasn't much salvageable in the motor when all was said and done. Metal shavings will reek havoc on a motor.
